Chapter 14 Configuring VLANs
Configuring Normal-Range VLANs
Assigning Static-Access Ports to a VLAN
You can assign a static-access port to a VLAN without having VTP globally propagate VLAN
configuration information (VTP is disabled). If you are assigning a port on a cluster member switch to
a VLAN, first use the rcommand privileged EXEC command to log in to the member switch.
Note If you assign an interface to a VLAN that does not exist, the new VLAN is created. (See the “Creating
or Modifying an Ethernet VLAN” section on page 14-8.)
Beginning in privileged EXEC mode, follow these steps to assign a port to a VLAN in the VLAN
database:
To return an interface to its default configuration, use the default interface interface-id interface
configuration command.
This example shows how to configure Fast Ethernet interface 0/1 as an access port in VLAN 2:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface fastethernet0/1
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 2
Switch(config-if)# end
Switch#
Command Purpose
Step 1
configure terminal Enter global configuration mode
Step 2
interface interface-id Enter the interface to be added to the VLAN.
Step 3
switchport mode access Define the VLAN membership mode for the port (Layer 2 access
port).
Step 4
switchport access vlan vlan-id Assign the port to a VLAN. Valid VLAN IDs are 1 to 4094; do not
enter leading zeros.
Step 5
end Return to privileged EXEC mode.
Step 6
show running-config interface interface-id Verify the VLAN membership mode of the interface.
Step 7
show interfaces interface-id switchport Verify your entries in the Administrative Mode and the Access Mode
VLAN fields of the display.
Step 8
copy running-config startup-config (Optional) Save your entries in the configuration file.
